Verdict
Constellation Map mobile and 星空ナビ both sit at 4.7 stars, but that hides the real split: 86% of Constellation Map mobile's written reviews are positive against 29% of 星空ナビ's. Constellation Map mobile also leads on ratings volume (4.6K vs 3) and iOS requirement (13.0 vs 15.1). 星空ナビ's advantage is ads (none vs shown). On price, rating, update cadence and in-app purchases there is nothing between them.
